Re: How to access calculation done in loop?

Hello, 
 try the example below.
Note, that it is not necessary to use node-set()
extension function in case of saxon (does conversion
automatically).

Best regards
Jirka


XML
<box>
 <item><qty>2</qty><price>3</price></item>
 <item><qty>3</qty><price>4</price></item>
 <item><qty>5</qty><price>6</price></item>
</box>

XSLT

<xsl:stylesheet 
  xmlns:xsl='http://www.w3.org/1999/XSL/Transform' 
  xmlns:saxon="http://icl.com/saxon" extension-element-prefixes="saxon"
  version="1.0">

<xsl:template match="/box">
 <xsl:variable name="all">
   <xsl:apply-templates select="/box/item" mode="qty_times_price"/>
 </xsl:variable>

 <result>
   <xsl:value-of select="sum(saxon:node-set($all)/tmp)"/>
 </result>
</xsl:template>

<xsl:template match="item" mode="qty_times_price">
 <tmp><xsl:value-of select="qty*price"/></tmp>
</xsl:template>

</xsl:stylesheet>


Output:
<?xml version="1.0" encoding="utf-8"?>
<result>48</result>

Best regards
Jirka
